Correction [to “‘On the ionospheric parameters which govern high‐latitude ELF propagation in the earth‐ionosphere waveguide’”]

CorrectionIn the paper 'On the ionospheric parameters which govern high-latitude ELF propagation in the earth-ionosphere waveguide' (Radio Science,14(5),8898908918928938948951979) the following corrections should be made: Equation (36a) should read u--> (a/2•r•,) [(1 -'V)(z -h,) + (36a) and (36b) should read ½--, (ia/2,r;,) [(• + •)(z-a,)-•,r•;,]In addition, a sentence in the first column of page 895 is not legible.That sentence should read 'For an exponential conductivity prof'de, the horizontal flow rate is essentially constant to an altitude ho, above which it falls off rapidly.'
